Abstract: Local observables of closed many-body quantum systems are generally believed to quickly equilibrate after a quench, according to the eigenstate thermalization hypothesis. Here, the authors show that the paradigmatic Heisenberg quantum magnet violates this fundamental… read more here.

Abstract: The influence of the anisotropic exchange interaction on the phase states of a non-Heisenberg ferromagnet with a magnetic-ion spin S = 1 is studied. It is shown that, depending on the relationships between the parameters… read more here.
